MTDiff: A Multi-Task Diffusion Accelerator With Bandwidth-Aware Memory Partition and Efficient Digital Compute-in-Memory

MTDiff: A Multi-Task Diffusion Accelerator With Bandwidth-Aware Memory Partition and Efficient Digital Compute-in-Memory 150 150
Author(s): Jiaqi Zhou, Yiqi Jing, Yiyang Sun, Siyuan He, Le Ye, Tianyu Jia

Abstract:

Initially applied to image synthesis, diffusion models have rapidly expanded into various content generation tasks, such as 3-D scene reconstruction and video generation, due to the superior generative quality. Based on our observations, the imbalanced operational intensities across diffusion model layers lead to suboptimal hardware utilization due to inadequate bandwidth …

A 92.1-dB SNDR Easy-Driving Two-Step NS-SAR-Based Incremental ADC With Concurrent Gain-Error Plus Noise Suppression

A 92.1-dB SNDR Easy-Driving Two-Step NS-SAR-Based Incremental ADC With Concurrent Gain-Error Plus Noise Suppression 150 150
Author(s): Chenyang Li, Tzu-Han Wang, Dongsuk Kang, Ken Li, Xitie Zhang, Wei-En Lee, Visvesh S. Sathe, Shaolan Li

Abstract:

This article presents a two-step incremental analog-to-digital converter (ADC) that achieves high resolution and energy efficiency while substantially easing the input driving constraints and interstage gain variation. By employing a level-shifted sub-ranging architecture with an input-tracking (IT) feature, the design obviates direct input sampling, thereby significantly relaxing the demands on …

BASS-PLL: A Bandwidth Augmented Sub-Sampling PLL Achieving a Wide Bandwidth Above 30% of the Reference Frequency and a Worst Case FoMREF of −247.9 dB at 3 GHz With a Ring Oscillator

BASS-PLL: A Bandwidth Augmented Sub-Sampling PLL Achieving a Wide Bandwidth Above 30% of the Reference Frequency and a Worst Case FoMREF of −247.9 dB at 3 GHz With a Ring Oscillator 150 150
Author(s): Tong Zhang, Yiwen Zhang, Xueke Cai, Weihao Jie, Yanling Zheng, Deyong Li, Yang Zhao, Yongfu Li, Honglan Jiang, Patrick P. Mercier, Hui Wang

Abstract:

This work presents a bandwidth augmented sub-sampling phase-locked loop (BASS-PLL) architecture that features simultaneous out-of-band noise suppression by direct and multipath sampling of the ring oscillator’s (ROs) output and in-band noise suppression via an intrinsic sub-sampling mechanism, ultimately combining the benefits of over-sampling PLLs (OS-PLLs) and sub-sampling PLLs (SS-PLLs) …

A 11.0-TOPS/W Diffusion Accelerator With Temporal Data Reuse for Real-Time Text-to-Motion Generation

A 11.0-TOPS/W Diffusion Accelerator With Temporal Data Reuse for Real-Time Text-to-Motion Generation 150 150
Author(s): Sungwoong Yune, Jieon Yoon, Hangyeol Lee, Adiwena Putra, Jaehoon Heo, Joo-Young Kim

Abstract:

Text-to-motion models are AI systems that generate human motion sequences directly from natural language descriptions, serving as key enablers for immersive virtual avatars and interactive digital humans in AR/VR ecosystems. However, state-of-the-art text-to-motion diffusion models suffer from substantial computational costs due to their iterative nature, making them ill-suited for …

0.13 K NETD D-Band CMOS Passive Imager With Noise Suppression Analysis

0.13 K NETD D-Band CMOS Passive Imager With Noise Suppression Analysis 150 150
Author(s): Zahra Mohseni, Sajjad Sabbaghi, Hai Yu, Peixin Han, Yuhao Yuan, Qun Jane Gu

Abstract:

This article presents a new system design and in-depth analysis of a wideband, low-power passive imaging receiver based on a Dicke-switch architecture, implemented in 28 nm CMOS technology. The proposed structure employs a three-coil gm-boosting technique for the low-noise amplifier (LNA). This approach reduces the LNA’s noise figure (NF) and …

Abstract:

Recently, 3-D human motion generation has become essential in media applications such as film production and augmented reality (AR)/virtual reality (VR) devices, requiring the generation of human joint movements and detailed 3-D meshes for each joint. Traditionally, joint creation required hours or even days, making it impractical for real-time …
